Specification of Letters Patent;

Patented Apr. 20, 19.20.

T 0 all whom it may concern:

Be it known that we, JACQUES SCHNEIDER and Fnnonmo BILLON, both citizens of the Swiss Republic, and both residing at Solothurn, Switzerland, have invented certain new and useful Improvements in High-Tension Distributors for Internal-Combustion Engines, of which the following is a specification.

The improved construction of high tension distributers that forms the subjectmatter of the present invention allows of considerably "reducing the space required for building-in the distributer, so that the distributer need not necessarily be overhung but may be built-in at any suitable point. This improved construction of the distributer affords important advantages from the manufacturing as well as the working point of View.

The essential feature of the improved construction consists in this that the fixed leads leading to the sparking plugs are arranged in two separate holders embracing the two lateral sides of the revolving distributor part, in such a manner that the said leads are located right and left of the said revolving part and are not inclined, or only very slightly inclined, to each other and so as to leave the upper and lower sides of the distributer free from leads. This improved arrangement efiects a great saving in space compared to the hitherto usual construction wherein the leads are arranged at equal angular distance around the entire periphery of the apparatus or around the upper half of the same. -At the same time, the advantage from a. manufacturing and working point of view is gained that the holders can be made of one and the same pattern for both sides and can be interchanged as desired.

Some constructional forms of high ten sion distributers according to this invention are illustrated by way of example in the accompanying drawings, in which 2- Figures 1 and 2 illustrate a distributor for a four-cylinder engine. The revolving part at composed of insulating material contains the contacts 6 which are arranged out of line with each other in the axial direction and inclose an angle a::90 with each other in the circular direction; these contacts e are connected to the high tension coil of the apparatus. The exit leads 9 with the exit contacts f are arranged side by side in the axial direction in pairs, one pair in each of the holders a and Z). in such a manner that the two pairs are situated diametrally opposite each other. The two holders a and b are separated from each other and fixed by means of the spacing piece 0.

The arrangement shown in Figs. 3 and l is suitable for asix-cylinder engine. The

corresponding parts are indicated in these and the following figures by thesanle letters as in Figs. 1 and The leads 9 are mounted in two groups of threes in the holders 1: and b respectively and so arranged that in each group two lead contacts are contacted in succession by one of the contacts e inclosing an angle a::, whereas only one lead contact is contacted by the other contact 6.

Figs. 5 and 6 illustrate an arrangement for an eight-cylinderengine. In this arrangement the leads 9 are attached in two groups of fours to the holders a and 6 respectively. The two pairs of leads of each group are arranged at an angle 3:4? to each other. The contacts 6 are shifted around through 90 to each other.

Figs. 7 and 8 and Figs. 9 and 10 show constructions suitable for twelve-cylinder engines. In Figs. 7 and 8 the six leads are arranged in two groups of three pairs each, the three pairs of each group being spaced apart at equal angles 30". The two contacts 0 are spaced apart circularly at anangle oz:90l

In Figs. 9 and 10 the six leads on each side are arranged in two groups of threes at an angle =30 between the groups. Correspondingly to the leads which are arranged in three planes at right angles to the axis, three contacts 6 are mounted in this case in the revolving part and they are spaced at angles. of 120.

The constructions shown in these figures are given by way of constructional examples of the invention, which may obviously be modified in view of the fact that the leads g which are arranged side by side in the axial direction may, together with'fthe contacts f, likewise be shifted around through any desired angle to one another. In such a case the angles a through which the contacts e are shifted relatively to one another in the circular direction must be modified to correspond.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is 1. In a high tension distributor for internal combustion engines comprising a cylindrical insulated rotating element carrying high tension leads connected to contacts arranged in varying angular positions on the surface of such cylindrical body, the combination with a pair of divided insulated segments partly surrounding the said cylindrical element and concentric therewith, having contacts on their inner. faces arranged in pairs around and in line with the contacts of the rotating element in var ing planes connected by leads to sparking p ugs, substantially as set forth.

2. In a high tension distributer for internal combustion engines, comprising a cylindrical insulated rotating element carrying high tension leads connected to contacts arranged in varying angular positions on the surface of such cylindrical body in combination with a pair of interchangeable segments partly surrounding and concentric with the rotating element having gaps at their upper and lower sides, free from leads, the upper gap provided with a fixing spacin piece inserted between said segments, su stantially as set forth.

In testimony whereof we have signed our names to this s ecification.
